TI - Design of Beam Focusing System with Permanent Magnet for J-PARC LINAC MEBT1 J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - Space charge compensation technology using higher-order multipole magnetic field components has been proposed to transport high-intensity charged particle beams for J-PARC LINAC MEBT1. In order to realize this compensation technology in a limited beam line space, we devised a compact-size combined-function multipole permanent magnet. This magnet can produce two multipole components at the same location on the beam line. As a first step, we have designed a magnet to simultaneously generate a fixed-strength quadrupole and an adjustable-strength octupole component using permanent magnet materials. In this magnet model, the magnetic circuit consists of two groups of magnets.
